English has a definite article ("the") and an indefinite article ("a" or "an").
Irish has only a definite article. In situations where "a" or "an" would be used in English, the noun is used with no article.
The definite article has two forms: an and na.
- an is used in front of singular nouns
- na is used in front of plural nouns (and feminine nouns in the genitive case).
The singular definite article "an" may change the noun it is applied to, depending on the first letter and gender of the noun:
(b c f g m p)
(d n t l r)
(s but not sc, sm, sp or st)
|Masculine||(no change)||(no change)||(no change)||t-/t|
|Feminine||séimhiú||(no change)||t||(no change)|
The plural definite article "na" changes the noun based only on its first letter:
|(no change)||"h" prefix|
